T 0 all whom it may concern;

Be it known that l, AUGUsriNE F. .lnrr inr'rnnn, a citizen of the United States, residing at Lynn, in the county of Essex and State of rangement ofmechanism: for trimming the marginal edge of an upper, and in a novel comb nation of trimming mechanism and means to posltion or to prepare the Work for the trimming operation. lnone important aspect, a feature oi'the invention consists in upper trimming mechanism constructed and arranged to co-operate in novel main ner with upper shaping means, for example end embracing wipers, whereby an upper is shaped over a form, to trim the margin of the upper while the upper is undercontrol of the shaping means. Among its objects,

the invention has in view the provision of means adapted foruse to trim the margin of an upper which extends in transverse relation to the plane of the bottom of a form over which the upper is shaped, or to the plane of an insole, as for example on welt shoe work where the marginal portion of the upper is shaped to provide an upstanding flange adapted to be sewed to the lip or rib of the insole. For-this purpose,-the construction herein shown comprises a cutter which is movable tovtrim the margin of the upper in a plane substantiallyparallel to the bottom of the former last or tothe plane of the insole. tive embodiment oi": the invention comprises a power driven disk cutter which is movable to cut outwardly through the upstanding margin of the upper and to trim the upper on a continuous line extending "from one side of the toe to the other's'ide substantially in I the plane of the outer face of the Wipers. In a further novel aspect the invention provides means for determining the positionot the More particularly, the illustracutter relatively to the work, comprising in the construction shown a member for engaging the insole to determine the plane of actionof the cutter relatively to the rib of the insole. I i

A further feature of the invention consists in means for guarding the edge of the cutter. As herein shown the cutter is mounted on the lower end of a vertical shaft which is embraced by a sleeve that affords con- I v venient means to be grasped by the operator in holding and guiding the cutter; The guard is mounted above the cutter to project normally beyond a portion of the acting edge of the cutter and a member connected to the guard extends in relation to the handle into such position that the operator can manipulate the guard therethrough by means of the fingers grasping the handle.

A further feature of the invention consists in novel means for controlling the operation of. the trimming means, the construction shown. comprising cutter operating means including a clutch through which rotary movement is imparted to the cutter while the cutter is in operative relation to the shoe or to the means, namely, the wipers, which hold the upper in position to be acted upon by the cutter, and disconnecting means automatically discontinuing driving of the cutter when the cutter is in inoperativerelation to the wipers or the shoe. As I am advised, moreover, it is new by this invention to providemeans for supporting a shoe and hold ing the marginal portion o'l an upper in position for the surplus thereof to be trimmed sist in novel means for supporting a trim-' ming device for movement relatively to a shoe, and in various details of construction and combinations of parts, all of which will now be described with reference to the accompanying drawings and pointed out in the claims.

Figure l of the drawings is a perspective view of one embodiment of the invention in a lasting machine of well known type.

Fig; 2 is a detail partly in section showing the trimming operation.

Fig. 3 is a side elevation, partly in sec tion, of. the trimmer driving mechanism,

and

Fig. 4 is a plan view of the rotary cutter with its guard. The shoe is herein shown as supported for operation between toe rest 2 anda hold-down 3. The toe lasting mechanism including the wipers 5 is employed 1 for.

forming the upper material to the toe of the last and compressing it upon the insole against the resistance offered by the sup portingtoe rest, which is raised and held in elevated position by connections with the power driving mechanism shown in Fig. 1 as shown and described more fully for example, in Letters Patent No. 1,373,482 granted on ripril 5, upon an application of Matthias Brock. In their usual operation upon welt shoes the wipers gather the upper inwardly over the feather of the insole and form it into a more or less upstanding, flange between the edge face of the wipers and the rib or shoulder of the insole. The effect upon the upper is to present it in approximately the position shown in the sectional view, Fig. 2.

The power driving mechanism includes acontinuously running pulley 10' from which a beltextends upwardly to drive a pulley 12 located above and at the rear side of the machine and sustained by the usual tack hopper supporting bracket of the machine. Above the pulley 12 is located a pulley 14 arranged to drive a pulley 15 journaled in the outer end of an arm 30 and having its spindle'connected by a flexible shaft 16 to a stem or shaft 18 on the lower end of which is mounted a rotary disk cutter 20. The pulley 1a is j ournaled upon the upper end of a shaft;l3 extending through and fixed in the tack hopper bracket with its lower end extending below said bracket. The pulley 12 loosely journals on the sleeve of pulley 14 (Fi 3).

The cutter is secured to the lower end of the shaft 18 by a stud or bolt 22, the lower end of which is rounded to adapt it for engagement with the tread face of the insole. This stud 22 may be caused to serve the purpose of gauging the height at which the cutter will trim the margin of'the upper, as illustrated in Fig. 2. The stem or shaft 18 of the cutter is shown as encircled by a sleeve 24: constituting a handle by which the perator can position and guide the cutter in trimming off surplus material progressively around the end of the toe.

A cutter edge guard 25 encircles the stem 18 closely adjacent to the top face of the cutter and is preferably of a diameter to extend slightly beyond the periphery of the cutter and thereby protect the work from injury by accidental engagement with the cutter. This guard is supported I y a vertical connecting member 26 fastened at the upper end of the sleeve, 24 and extending down the side of the sleeve in position to be engaged by the operators fingers and allow the operator by such engagement to retract the, gage fromv and expo'se the portion of theedge'of the cutter whichhe desires to have engage with the stock to be out. The member QGispreferably of spring metal and operates to return the guard automatically toworking position when released from pressure by the operators fingers.

The arm- 30 extends from the pulley shaft 13 and is swiveled so that said arm and the cutter can swing backwardly and away from the shoe into a position in which they are out of the duringthe lasting operation. The arm 80 is not directly connected to the pulley shaft l3 but is pivoted on a bracket that has a base embracing and journaled on the lower end of pulley shaft 13 and supported upon the upper face of a washer fixed to the lower extremity of shaft 13. A spring 32, Fig. 3, sleeved on this washer with one end fixed to the washer and its other end secured to bracket 85, normally tends to return the arm backwardly and away from the shoe. A spring 36i s interposed between the bracket 35 and arm 80' and operates to hold the armnormally in an upraised position, allowing the operator to lower the arm and the cutter to the desired position for the work to be performed. Preferably also the pulley 14 is loose on the pulley shaft 13 so that it, and therefore the cutter, is normally idle; This reduces the danger of injury to the work or to the workman which would arise from a continuously rotatii'lg knife, even when the knife is swung ba ck to an inoperative position. A cone clutch, shown in section in Fig. 3, is provided for connecting the pulleys l2 and A. The inner member of the clutch is formed on the continuously running pulley 12, which pulley is mounted to have a short vertical niovement on the shaft--13, being held in its depressed position by a spring 37. The pulley 12 has a lower face adapted to be engaged by rolls onthe rear varms of a forked lever #10 pivoted on the bracket 35, the front arm of which lever extends under the swinging arm 30. A spring 42 is interposed between said arm and the underlying arm of the lever. A rigid finger 41 projects from the fOljMl lever approximately parallel to the arm 30, its end extending over a lug laterally offset from the arm 30. A set screw is carried by and depends from the end of said finger to be engaged by the lug 43 upon the upward movement of arm 30 positively to move downwardly the clutch operating end of lever an to permit the clutch spring 37 to operate to throw out the clutch. The position of the lower end of the set screw may be adjusted to suit the strength of the spring 36 and'to compensate for weakening of the naeenoe spring. The set screw and the spring e2 provide a connection between the depressi ble arm 30 and the clutch operating lever 4-0 so that when the arm 30 is depressed to bring the cutter into operative relation to a shoe on the toe rest, the lever All) is rocked to close the clutch and cause the cutter to be rotated.

In the contemplated use of the machine, a shoe is positioned upon the power operated toe rest and is clamped between said rest and the hold-down. The lasting wipers are then manipulated to form the upper around the toe of the last and advanced by the hand lever 7 to wipe the upper into the position shown in 2 and hold it for the operation of the cutter. When the upper has been satisfactorily lasted to the shape oi? the particular last upon whichthe shoe is being made, the surplus portion at upper materials extending above the wipers can be accurately cut away on that particular shoe, thus leaving the shoe in the best possible condition for the welt sewing-on operation. The operator now seizes the handle portion of the cutter and swings thefcutter over the shoe bottom, depressing it until. the gage 22 contacts with, the insole inside of the gathered margin of the upper and then slidinp; it forward and moving; it around the toe to cause the cutter to trim off the upper materials at the elevation provided for by the stud 22. The cutter may thus be Q'uided to cut outwardly through the flange of the upper at one side of the toe and then to trim progressively round the to the other side. The guard 25 protects the of the cutter until the opera-i;- r presses it back and uncovers the cutter for the trim-- minp,- operation. The closed wipershold the upper against the thrust of the cutter and act as a shear blade to assist in insuring; a clean cut by which the surplus mat rial entirely disconnected from the shoe. cutter preterably acts substantially in the plane of the top face of the wipers and it desired the wipers can be employed as a with. reference to which the cutting can be done instead of employing the gage 22 for that purpose. When the trimming operation has been completed, and with the construction and organization illustrated this is done very quickly, the operator releases the cutter and it is swung; back out of the way by the action of spring 32, while spring; 36 raises the cutter carrying arm 8-1} sufficiently to open the clutch.

The rotary disk cutter 20 illustrated here in I find particularly advantageous in that'it provides a series OfSDttCGtl cutting edges or teeth which will bite into the upper mate ials and quickly cut through the double thickness of upper and lining. These series of teeth are formed by grindingout or otherwise forming in the face of the disk cutter a series of spaced depressions with conca outer edges which merge into the adjacent convex cutting edges of the disk and form a series of cutting teeth with clearance notches between the teeth of the series.

If desired, the surplus upper stock may be removed after the toe has been wired, and it may be also after the shoe has been removed from its support, the workman grasp ing the shoe and manipulating the cutter to trim off the surplus materials in the manner previously described. While it is prelierable to effect the trimming operation with the shoe supported as described because oi the co-operative relations of the parts and the convenience and saving of time adorded by such relations, it will be understood that, except as expressly stated by ornecessarily implied from the claims the invention is not limited to these trimming and supporting instrumentalities in combination. I

While the invention is herein illustrated and described with particular reference to trimming oil the surplus margin of the upper at the, toe end of the shoe, it is not intended thereby to imply any limitation with respect to such features of the invention as are clearly of utility irrespective oi the particular portion of the shoe upon which the trimming operation is performed.
